INK-WELL..

` `Application filed April 4, 190i..

useful Improvements in Ink-Wells; and I do hereby declare the followingto be a full, clear, and exact description ofthe invention, such as willenable others skilled in the artto which it appertains to makeand usethe same.

My invention relates to inkwells of the ba'- rometer type,whe'rein theink is supplied from the ink-reservoir to the well proper propor-4tionately as it is used from such wells; and the object is to provide anink-well of this character in which the; inkreservoir is independent ofand detachable from the well.

My invention consists of a Well having an auxiliary reservoir attachedtothe top of the same in an inverted position, the well proper having acontracted neck intermediate of its ends and the dipping-pit extendingabove said neck, thereby preventing'the too-rapid flow of the ink intothe dipping-pit.

Fora full understanding of the merits and advantages reference is to behad to the following description and accompanying drawings, in which-Figure 1 is an isometric perspective. Fig. 2 is a longitudinal sectionalView showing the parts assembled. Fig. 3 is a top View of the wellproper, showing the opening. Fig. 4 is a side elevation of Fig. 3; Fig.'5 is a detail view of the neck of the reservoir. Fig. 6 is asectiontaken on the line X X of Fig. 2, show-A ing the membersinterlocked. Y

Like characters of reference indicate corresponding parts throughout theseveral views.

A indicates a hollow vessel forming the ink'- reservoir, having the necka, the endof which is provided with an annular mutilated shoulder, as ata', leaving the parallel flattened edges a oppositely disposed. Beneaththe reservoir A and secured thereto' is the well proper, B, having .thedipping-pit b, merging from the contracted portion b.

In the top of the well is formed an opening C, surrounded by'anupstanding neck, which is provided with curved ends and twoOppositely-disposed parallel straight sid es c and c.

Serial No. 54,365. (No model.)

`Beneath the straight sides of the upstanding neck are formed inclinedshoulders c", which are inclined in opposite directions, so as totightly draw the reservoir A down upon the neck of the well B when theshoulders a on the neck of lthe reservoir A are engaged thereby. Theopposite straight edges on the neck a of the reservoir A correspond tothe straight edges in the opening C of the well B, and when the neck a.is inserted within the opening C the straight edges of veach areparallel, but by giving the reservoir a partial turn the shoulder a'will engage the inclined shoulders c in the well, and these shouldershaving inclined faces will cause the parts to be tightly assembled andrender the dislodgment ofthe same almost impossible. A suitable packingD may be applied upon the neck a to contact with the other edge of theopening C, and thereby prevent leakage.

When the parts are assembled, as above described-the ink will entirelyfill the well anddipping-pit, and the dipping-pit being only largeenough for the insertion of the pen will expose'only a small quantity ofthe ink to the air, and thus prevent the thickening and evaporation ofthe sameby its contact with the atmosphere, by which the flow of the inkis retarded.

It will be apparent that the ink is supplied from the reservoir to thedipping-pit propor- .tionately as it is used, there always being thesame quantity of ink in the dipping-pit and alwaysat a uniform depth, sothat the pen receives the same amount of ink at each in- Itis alsoobvious that the parts can -be readily cleaned, as they are detachable,

and the filling ofV the` reservoir is greatly facilitated. 4

`The entire well is adapted to rest upon a suitable metallic base 1,havinga depression 2 therein to conform to the shape of the bot` torn ofthe well and provided with openings 3, in which the arms et areinserted.Each of these arms is provided with a lug 5, which rests upon the top ofthe base laround the edge of the openings 3 and supports the arms 4. Theupper portion of the arm is extended rearwardly, disposed in ahorizontal plane,

and provided with tbe protuberances 6, between which penholders Vareadapted to be p1aced,therebyproviding a suitable pen-rack.

Having thus described myinvention, what I claim is- 1. In au ink-Well,the combination with a reservoir having a neck provided with a mutilatedshoulder, of a well having,r an opening surrounded by an npstandingneck, said neck formed with curved ends and two oppositelydisposedstraight sides, and inclined shoulders beneath the straight sides to beengaged by the shoulders on the neck of the reservoir to lock the partstogether and a suitable packing between the reservoir and the well,substantially as specified.

v2. An ink-well of the barometer type comsemina prsing a Well properhaving a contracted portion and a dipping-pit merging therefrom, anopening formed in'the top of the Well and provided with inclinedshoulders beneath its edges, a reservoir mounted on top of the Well andprovided with a shouldered neck adapted to engage the inclined shouldersof the Well and a suitable packing between the contiguous faces of thereservoir and well, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
